We see lightning flash in front of a castle. A baker put a dollop of icing on a tiny pig cupcake while a shadowy figure lurked behind her. Another lightning strike caused her to panic, and we saw another worker come to help her clean. They are both surprised when a third worker put a drink on the tray the baker prepared. He clapped his hands, and a robot dropped from the ceiling, grabbing the tray.
It delivers the food and drink to Entrapta, who uses her prehensile hair to eat and drink. She interacted with a First Ones' artifact, a Data Disk, using a fancy computer. She recorded a video message, saying this could contain the secrets of the First Ones. Red vines started growing out of the artifact, covering Entrapta's computer and turning the screens red. This sent out a blast and activated an alarm on top of the castle. Her robots' eyes turned red, and they started surrounding Entrapta. Entrapta exclaimed that the robots are responding to her code. The delivery robot broke her trash can, and threw it at Entrapta as she mused about making modern and ancient technology compatible. As a mass of robots gathered in front of her, she announced in her log that she is going to run.
Adora, Glimmer, and Bow traveled to Dryl to recruit Entrapta to the Princess Alliance. Upon arriving to Dryl they saw the distress beacon, and She-Ra tripped one of Entrapta's traps but evaded it. There was some loud banging and one of the residents told them to get out of the square, they were attacked by one of the infected bots. Glimmer and She-Ra fell into one of the traps, but Glimmer teleported them out. At the same time Bow was rescued by the three people working in Dryl by taking him to the kitchen. Entrapta introduced herself to Glimmer and She-Ra.
Entrapta activated her giant cleaning bot with a hand clap, but then it attacked them. She-Ra destroyed the bot and when the Sword of Protection touched the infected bot the infection traveled to the sword and caused She-Ra to go berserk. Glimmer wrestled the sword from She-Ra who transformed back to Adora, leaving Adora in a stupor. They went to the lab but could not get in since the door locked Entrapta out and booby-trapped itself.
Baker, Soda Pop and Busgirl, and Bow defended the kitchen from the bots, which Bow's Tracker Pad attracted by making noise. They then made their way through Dryl and fought many bots. When the staff grew fearful Bow gave a rousing speech, recruiting them into The Rebellion. All the heroes met up and fought off many, many bots together in the halls of Dryl.
The six heroes got into the lab, where the disk had built up a protective barrier and began powering itself. Bow shot the disk with his sonic arrow and the bots responded to the loud noise by attacking the arrow; the bots broke the disk while assaulting the arrow. This uninfected all the bots, the Sword of Protection, and Adora.
- The mines of Dryl are mentioned, which first appeared in the original She-Ra: Princess of Power episode The Price of Freedom.
- She-Ra herself is not directly infected by The First Ones' tech; the Sword of Protection is what gets infected by the Data Disk and passes the infection to She-Ra. The only way to fix the infection is to destroy the Data Disk.
